Is there a bit of instructions somewhere on what I would need to configure to get the API to show up on the networked device?
I have an Avalon and I have API Allow enabled on the the unit but I am not sure what to do from there.
Thanks
Okay folks - time to ask for help from those who like to live on the edge  

Version 2.6 of MultiMiner will include, among other things, 
automatic detection of network miners, e.g. AntMiner S1, MinePeon, etc. There is absolutely no configuration in MultiMiner. As long as the device is configured to allow API access, it should show up automatically in MultiMiner within a minute or so.
Here is a pre-release with the basics of this feature completed.
Thanks in advance for the feedback!
Version 
2.6 PR2 (pre-release) is now available for testing for those with the time  

 This feature is now completed for 2.6 so any feedback is very much appreciated. The rest of the features for 2.6 will involve MultiMiner Remoting.
Network Device Discovery
Download link:
https://www.dropbox.com/s/akpsic6sru66mqe/MultiMiner-2.6.0.zipThis feature is - for now - completely automated. MultiMiner will automatically find RPC API servers on the local network. It will automatically filter out both its own miners and any miners pointed at its own Stratum Proxy. For now the UI assumes that these Network Devices are mining Bitcoin, though that will be expanded upon in the future.
Please, if you have time, kick the tires on this and let me know if you find any issues. This build also includes all of the latest fixes from the 2.5 versions.
Edit: I've updated the above download link with Version 
2.6 PR3. This includes a few minor fixes as well as support for installing MultiMiner and bfgminer updates on all of your rigs at once via MultiMiner Remoting. Now this feature has the chicken-and-egg scenario - it won't kick in until the next public version is available. However, if you get your rigs on this 2.6.0 PR3 now, once 2.6.1 drops you should be able to update all your rigs with a single click.
